The longest Amtrak route available runs from Chicago to New York. As first noted by MacRumors, other supported routes with transit directions include the Northeast Regional, Acela Express, Keystone, Lake Shore Limited, Pennsylvanian and Maple Leaf.

Many of these routes operate between major cities in the Northeastern United States. “Amtrak routes in the South, West, Midwest, and Northwest are not currently available in Apple Maps, but the information will likely be implemented as Apple expands transit information to additional areas across the United States,” posits the publication.

Boston, one of the cities originally included in Apple Maps transit launch but later removed, has now been added to Apple’s information stack for Maps transit directions.

Transit directions are currently available in Apple Maps for iOS 9, OS X El Capitan and watchOS 2 in Baltimore, Boston, Chicago, New York, Philadelphia, Washington, DC and San Francisco in the United States, and in 300 cities in China.
